Milky Way Near Twins (MWNeTs). I. A Hierarchical Framework for Identifying the Evolutionary Counterparts of the Milky Way
I. B. Vavilova, A. M. Dmytrenko, D. V. Dobrycheva +8
The search for Milky Way (MW) analogues has traditionally relied on similarity in a limited set of present-day global properties, including morphology. However, galaxies with simil…
NGC 3521 as the Milky Way near twin: spectral energy distribution from UV to radio decameter ranges
O. V. Kompaniiets, I. B. Vavilova, Y. V. Vasylkivskyi +10
Milky Way analogues (MWAs) are usually selected from structural and kinematic properties, but robust SED-based similarity criteria are limited by heterogeneous photometry and incom…
Galaxy rotation curve based on RGB stars from the Gaia DR3 catalogue
P. N. Fedorov, A. M. Dmytrenko, V. S. Akhmetov +8
In this paper, we construct a detailed circular velocity curve of the Milky Way out to 20 kpc based on the radial component of the Jeans equation in cylindrical coordinates, assumi…
Discovery of the Polar Ring Galaxies with deep learning
D. V. Dobrycheva, O. O. Hetmantsev, I. B. Vavilova +3
The aim of our research is to create a catalog of strong and good candidates for PRGs using existing catalogs of PRGs, develop an image-based approach with machine learning methods…
Spatial orientation and shape of the velocity ellipsoids of the Gaia DR3 giants and subgiants in the Galactic plane
A. M. Dmytrenko, P. N. Fedorov, V. S. Akhmetov +8
We present the results of determining the parameters characterizing the shape and orientation of residual velocity ellipsoids from the Gaia DR3 red giants and subgiants. We show th…
